Atomtronic Circuits of Diodes and Transistors in Physic Review Letters. From Physorg: Atomtronics probably won’t replace electronics. “Atoms are sluggish compared to electrons, and that means that you ...

Started building my first hobby circuits at age 11 using the venerable 1N34A diode & 2N107 transistor. In high school, I knew more than the teacher so I taught my physics class electronics--LOL. Still ...
